SM8250 requires special power domain for accessing MMDS_GDSC registers.

Heh, not sure it's special.

Add bindings for the MMCX power domain.

Do we need this node in the example? I think it isn't required but I
guess it's OK.

It is to be able to resolve "power-domains" and "required-opps" properties values.
